Strategic Carbon co-founder Dr. Richard Coffin led the 11th International Workshop on Methane Hydrate Research and Development in Corpus Christi, Texas.  This workshop was created for hydrate researchers and stakeholders to freely exchange information and identify research priorities in an effort to promote collaboration. The past ten workshops have been co-organized by Professors Bjørn Kvamme (University of Bergen, Norway), Tsutomu Uchida (Hokkaido University, Japan), Stephen Masutani (University… Read more »

Strategic Carbon co-founder Dr. Richard Coffin and Dr. James Mueller (Provectus Environmental Products, Inc) conducted field sampling that focus on a cleaning facility near Detroit, Michigan.  Provectus Environmental Products’ field bio-enhancement remediation technology was evaluated as a source of high methane concentrations below manhole covers near a treatment site. Stable carbon and radiocarbon isotope analysis developed and tested by Strategic Carbon experts was applied to assess… Read more »

Carbon isotope geochemistry is applied to understand spatial variation in tundra and methane contribution to coastal shallow sediment cycling across the Alaskan Shelf in the Beaufort Sea. This study shows strong spatial variation in the carbon sources that is a function of tundra melting and riverine input and past ice scouring that is driving sediment deposition and methane production. → Go to Full Report

Strategic Carbon co-founder Dr. Richard Coffin joined a contract with several companies to apply his isotope geochemistry background to assess long-term organic contaminant source distribution and residence time through the Hackensack River in New Jersey. Work done on this closed project will address New Jersey Environmental Regulations for which the supporting company is responsible. This work does show a strong development in basic specific compound isotope… Read more »

Methane concentration and stable carbon isotope ratios measured from ice and ice free waters along the Alaskan Shelf in the Beaufort Sea between 1992 and 2009 show strong spatial variation in flux rates to the atmosphere.  Isotope analysis indicated the primary source of the methane is bacterial.  The estimate from this region on the total contribution to the atmosphere is only 0.42% of the total annual loading of… Read more »

Dissolved organic matter (DOM) absorbance and fluorescence were used as optical proxies to track terrestrial DOM fluxes through estuaries and coastal waters by comparing models developed for several coastal ecosystems. Key to using these optical properties is validating and calibrating them with chemical measurements, such as lignin-derived phenols—a proxy to quantify terrestrial DOM. Utilizing parallel factor analysis (PARAFAC), and comparing models statistically using the OpenFluor database… Read more »

Company hosts senior delegates at Columbia University The founders of Strategic Carbon, a Portsmouth-based science and environmental consulting company, last week hosted a two-day technical workshop at Columbia University for high-level management from CNPC (China National Petroleum Corporation), China’s largest oil and gas producer and supplier. With extensive experience in new energy commercial applications and backed by global academic alliances, Strategic Carbon organized the workshop at… Read more »

Iodine-131 (t1/2 = 8.04 d) is widely used in nuclear medicine, primarily to treat hyperthyroidism and thyroid cancer, with an annual average of 188 treatments per million people in developed countries. The administered dose of Iodine-131 (∼0.1−1 and 4−8 Gbq for hyperthyroidism and thyroid cancer, respectively) is metabolized by patients and eliminated from the body mostly in urine. In the United States, patient excreta are exempt… Read more »

Sediment organic carbon composition and provenance have been extensively studied in the Gulf of Mexico. Generally, inputs of terrestrially-derived organic carbon dominate near shore sediments and decrease with distance offshore where water column phytoplankton dominate contributions to shallow sediments. For this study shallow sediment and porewater samples were collected from Atwater Valley, Texas-Louisiana Shelf, Gulf of Mexico near a seafloor mound feature identified in geophysical surveys as… Read more »

The Chatham Rise is located offshore of New Zealand’s South Island. Vast areas of the Chatham Rise are covered in circular to elliptical seafloor depressions that appear to be forming through a bathymetrically controlled mechanism, as seafloor depressions 2–5 km in diameter are found in water depths of 800–1100 m. High-resolution P-Cable 3D seismic data were acquired in 2013 across one of these depressions. The seafloor… Read more »
